A two-dimensional atrial tissue model has been constructed in COMSOL Multiphysics® software to study the propagation of action potential and electrograms. The model presents the atrial electrograms recorded with a mapping catheter.
A 2D atrial tissue model is simulated using the Courtemanche et al. cell model equations. PDE in coefficient form was used in COMSOL Multiphysics® to reproduce ...

The aim of this work is to present a model capable to describe the behaviour of a thermal flow sensor under every physical aspect.
A generic thermal flow sensor relates the flow properties with a variation in the temperature profile inside the device itself. Thus, it is locally heated up with a resistive element biased with an external current, surrounded by one or more temperature sensing ...

Rotor blades for wind turbines are made of GFRP material. They have to be designed to withstand wind and weather over their approximately 20 years of lifetime. The ability to monitor the mechanical stress is crucial in order to reduce maintenance costs and to maximize operational availability.
This paper presents the combination of SPICE® and COMSOL Multiphysics®, in order to reduce ...

Surface plasmon resonance (SPR) sensors proved themselves as a promising device for many kinds of applications such as optical biosensing, binding constant determinationor nanofilm thickness measurements. Here we simulate using COMSOL Multiphysics® the light-polaritons coupling for the two most commonly used SPR setups: Attenuated total reflection (Kretschmann configuration) and diffraction ...

Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis (based on mathematical formulas) can be uncertain. The applied FEM method of the analysis can be a solution to ...

Induction furnaces are employed for vacuum distillation process to recover heavy metals after electro-refining operation. Induction furnace of suitable heating rate and cooled by passive means are required to be developed for this purpose. It is planned to set up a mock up induction furnace which will simulate the conditions to be realized in actual vacuum distillation furnace for this purpose. ...

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low frequency (10 Hz) light flicker. Our aim is to calculate the acoustic streaming velocity field, which is related ...

For a proper design shaping of light emitting diodes, the exact knowledge of the current distribution in the active area is essential. On the one hand, one has to achieve a uniform current density over the chip area, on the other hand, one has to avoid current crowding in the neighborhood of the electrical contacts. In this paper it is shown first how a LED can be modeled by COMSOL Multiphysics. ...

A specific issue in transformer modeling using the finite element method is the consideration of electric sheets or other laminated core materials which are used to reduce eddy currents. It would be impractical to explicitly model a large number of sheets as this would lead to a large number of elements and hence to unacceptable computational costs. Homogenization procedures overcome this ...

Finite element modeling of three phase three limbed transformer requires solving of field and circuit variables simultaneously. The accurate modeling thus obtained could predict asymmetry in magnetizing current of three phases due to asymmetry in core of three limbed transformer.
This work includes circuit field coupling using COMSOL Multiphysics’ ACDC module. By proper modeling in SPICE it ...
